Phoenix loves his job. A company has hired him to exterminate vile creatures in an old underground complex. The rules? There are none. If fact, the bloodier the better. The animals have no idea an expert is hunting them down, one by one. To Phoenix this is paradise, being able to do whatever he likes and have the protection of the company. The creatures do whatever it takes to survive, after all, they are human. With many eyes watching everything, Phoenix does his job well, painting with blood and having fun with brutality. Thirty dwellers of the complex scatter like roaches, but find they must unite to neutralize this sadistic killer. With nowhere to escape, they are trapped, in a game of red.
